JAMES F. GOODRIDGE, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO CHARLES .l.ROLFE, OF CAMBRIDGE, MASSACHUSETTS.

CASH REGISTER, INDICATOR, AND RECORDER.

SPECIFICATION forming part of Letters Patent No. 557,577, dated April 7,1896.

Application filed July 23,1894. Serial No. 518,292. (No modeL) To aZZwhom it may concern:

Be it known that I, JAMES F. GOODRIDGE, of Boston, county of Suffolk,State of Massachusetts, have invented an Improvement in Cash Indicatorsand Registers, of which the following description, in connection withthe accompanying drawings, is a specification, like letters on thedrawings representing like parts.

IO This invention has for its object to provide an improved andsimplified cash indicator and register.

I11 its preferred form my invention comprehends a machine which not onlydisplays the [5 amount of sale to the purchaser, but also adds or sumsup the total amount of sales, and prints or records, in suitable manner,upon a paper strip or otherwise, the amount of the sale, though I desireit to be understood that machines embodying my invention may be usedemploying with the devices for indicating the amount of sale to thepurchaser devices for adding or summing up the total sales without theprinting or recording mech- 2 5 anism, and vice versa, with the printingor recording and without the adding mechanism.

One of the principal features of my invention relates to the devices forindicating to the purchaser the amount of the sale.

Cash indicators and registers as usually constructed may, so far astheir operation is concerned, be classed under three headsviz., those inwhich the amounts of purchase are set or indicated by the depression ofvarious key-levers, those in which the said amounts are fixed andindicated by rotation of apointer upon a dial upon which are displayedthe several amounts of purchase, and those in which the amounts ofpurchase are fixed and indicated by the rotation of one or more disks bymeans of handles thereon and upon which the various charactersrepresenting the amounts of purchase are displayed. In all machines ofeither of these classes, so far as 5 known to me, it is necessary tofirst fix and display the amount of purchase before the money or changedrawer can be opened, and in all of them, as I believe, the amount ofpurchase is necessarily displayed before the drawer is moved. In myexperiments to perfeet apparatus of this kind I have found it to bedesirable to conceal the amount of purchase from the purchaser until thesalesman has been forced to open the drawer, make the proper change, andagain close the drawer, I having found this to be a needed safeguard.

One of the principal features of my invention therefore consists inproviding the apparatus with suitable mechanism for visually indicatingto the purchaser the amount of the sale or purchase, which mechanism isso constructed that it is first fixed or selected before the drawer canbe opened, but remains concealed from view until the drawer is moved,movement of the drawer causing the exposure of the fixed or selectedcharacter or characters. In connection with this I preferably employsuitable devices to compel the drawer, when once started, to be fullyopened and again fully closed.

In the preferred embodiment of my invention the several charactersrepresenting various amounts of purchase are arranged upon a rotatingwheel, which wheel is suitably mounted upon a shaft adapted to berotated by a pointer sweeping over a suitable dial upon which arecorrespondingly arranged other characters indicating the amounts ofpurchase.

All the characters of the wheel, except the one showing the amount oflast purchase, are in this construction normally concealed from View,rotation of the pointer at each sale bringing the character representingthe amount of such sale into position adjacent the 8 5 view-opening,though still concealed from view therethrough, subsequent movement ofthe drawer acting to expose the character thus fixed or selected at thesaid opening.

In the preferred embodiment of my invention a type-wheel, upon whichtype-characters are arranged to correspond with the arrangement ofvisual characters on the inclicating-wheel referred to, is mounted uponthe pointer-shaft and rotated thereby, and suit- 5 able printingmechanism actuated by movement of the drawer cooperates therewith topermanently record or print upon a continuous or other strip thesuccessive amounts of purchase.

My invention further comprehends a suitable adding device, movement ofwhich is fixed or determined by the selecting mechanism and afterwardoperated by movement-of the drawer.

These, together with other features of my invention, including variousdetails of construction, will be more fully hereinafter described, andset forth in the claims at the end of the specification.

In the drawings, Figure 1 represents in face View one and the preferredform of machine embodying my invention; Fig. 1, a detail of the same,showing the selected character 5 moved into position adjacent, butconcealed from view at the view-opening; Fig. 2, a top or plan view ofthe machine shown in Fig. 1 with the inclosing case removed; Fig. 3, avertical section taken on the dotted line a: as, Fig. 2; Fig. 3, aperspective detail showing the cam H and its connections for actuatingthe adding mechanism, but in a different position from that of the otherfigures; Fig. 4, a vertical section taken on the dotted line 41; as,Fig. 2, looking toward the rear of the machine; Fig. 5, a verticalsection on the dotted line 50 Fig. 2, with the front of the inclosingcase,ineluding the fixed dial, removed; Fig. 6, a vertical section takenon the dotted line 09 00 Fig. 5, showing the adding mech anism inelevation; and Figs. 7 to 10, inclusive, sectional details taken,respectively, 011 the dotted lines 1 y, f, and 1 Fig. 5, showing theconstruction and illustrating the op eration of the adding mechanism;Fig. 11, a detail showing mechanism for exposing the selected visualcharacters.

Referring to the drawings, in the particular machine there shown asembodying and illustrating my invention A is a suitable case containinga usual money-drawer a, adapted to slide in and out of the same, saiddrawer being provided with a suitable handle a. (Shown best in Fig. 3.)Inasmuch as the parts are locked when the drawer is closed, and the saidlocking mechanism is operated by movement of the drawer, as will bedescribed, it is necessary to first partially open the drawer to releasethe locking mechanism before the visual indicating-characters, printin gand adding mechanism, either or all, may be set or selected, and it isfurther desirable to compel the salesman to make the proper selection ofcharacters before he has completely opened the drawer. To accomplishthis I have provided a lock to stop the drawer when it has beenpartially opened, to indicate to the salesman that he must then stop andselect or display the visual character indicating the amounts ofpurchase, after which he releases the lock and completes the opening andclosing of the drawer, the locking mechanism previously referred torequiring full opening of the drawer when once started before it can beclosed.

The locking device herein shown to stop the drawer after partial openingof the same consists of an Lshaped lever a pivoted at a on the drawerand acted upon by the spring a one end of the said lever in the presentinstance being hooked, as at a to engage a stop a on the bottom of thedrawer-case.

The finger end of the said locking-lever, whenv the drawer is closed, isconcealed by a suitable plate a on the case, as shown.

The drawer may be opened without releasing the locking device until inits movement the hooked end a of the locking-lever engages the stop a,after which, the proper visual character having been selected, the saidlever is moved to disengage it from said stop to permit farther openingof the drawer.

Mounted upon the inclosing case A are the front and back frame-plates bb, there being two of the latter, in which plates is j ournaled the mainor pointer shaft B, provided at its front end with a suitable pointer 1)adapted to sweep over a fixed dial b on the face-plate of the inclosingcase, the said dial having circularly arranged thereon, as best shown inFig. 1, characters 19 representing the amounts of the several purchases.

Loosely mounted on the pointer-shaft B and connected therewith bydevices to be described is an indieator-wheel 0, (see Figs. 1 and 5,) atthe periphery and upon the face of which are displayed, as shown indotted lines, Fig. 1, and full lines, Fig. 1, visual characters 0 alsorepresenting amounts of the several purchases, but arranged in reverseorder to the arrangement of the corresponding characters on the fixeddial W. The indicator wheel a has also at its rear side a second seriesof characters of the same denomination as those at the face of thewheel, but necessarily arranged in opposite or reverse order, thearrangement of the characters at the back of the wheel corresponding inevery respect to the arrangement of the characters 011 the face of thedial h The indicator-wheel c is herein concealed or inclosed in asuitable inclosing case or shell 0, (see Figs. 1 to 3,) which inclosingcase is provided at its opposite sides, and preferably at its highestpoint, with visual or sight openings 0, (see Fig. 3,) shown directlyopposite each other, only one of which is shown in Fig. 1, and throughwhich one of the characters of each series of the indicating-wheel maybe exposed at the proper time.

Referring now to Figs. 1", 3, and 5, the pointer-shaft B has fast uponit a hub b provided with two projecting ears b holding between them apin 0 on the hub of the indicating-wheel c, the distance between the twoears 19 being considerably greater than the diameter of the pin 0 toprovide a lost motion equivalent to the space occupied by any characterupon the indicating-wheel. A spring 0 on the hub of the indicating-wheelbears against one of the cars 11 and tends to keep the pin 0 normallyagainst the left-hand ear 6 Figs. 1 and 5, said pin, however, being attimes positively moved against the other of the said ears by rotation ofthe'indieating-wheel on and with relation to the shaft IOC B bymechanism and for a purpose to be described.

Upon the hub of the indicating-wheel I have fixed a ratchet-wheel 0 (seeFig. 11,) with which cooperates a pawl c pivoted at c on the end of alever 0 in turn pivoted at c to an arm 0 of the front plate, the saidlever 0 having jointed to it the upper end of a vertieal slide-rod 0mounted in suitable bearings in the front frame-plate and provided atits lower end with a roller 0 adapted to travel on the top of the track0 on the money or change drawer, said slide-rod being normally depressedto keep its roller 0 in operative contact with the said track by aspring encircling the said rod and acting at one end against the arm 0and at its opposite end upon a collar 0 fast upon said slide-rod.

By reference to Fig. 3 it will be noticed that the track c, near thefront of the drawer, has a slight rise, so that when the drawer iswithdrawn the roller o trails down the incline of the track, upon thelevel portion thereof, and thereby drops the vertical sliderod 0 and itspawl c to permit the spring 0 to turn the indicating-wheel to the left,Fig. 5, following the retreating pawl c until its pin 0 contacts withthe other or left car 19 on the pointer-shaft, as in Fig. 1, so thatwhen the drawer is open, however little, the pin 0 is always in contactwith the left car 11 as there shown. If, now, the pointer Z) be turnedto any particular character on the fixed dial, to thereby rotate thepointer-shaft to bring the indicatingwheel into position to subsequentlyexpose the corresponding character thereon, it will be found that theindicatingwheel will be rotated not quite sufficient to expose thedesired character, leaving the same adjacent the view-opening c in theinclosing case, but concealed by the side wall of the said case, asshown in Fig. 1. Then, however, the money-drawer is subsequently closed,the roller 0 on the vertical slide-rod e rides up the incline of thetrack 0 and again raises the pawl 0 causing it to turn the ratchet-wheeland its attached indicatingwheel to the right, Figs. 1 and 5, on theshaft 13 through a distance represented by the lost motion between thepin 0 and the ears b or until the said pin contacts with the right earZ1, such auxiliary movement being suiiicient to bring the desiredcharacter from its concealed position,-Fig. 1, into exposed position,Fig. 1, back of the view-opening to visually indicate to the purchaserthe amount of the purchase.

The operation of turning the pointer to bring the desired character intoposition adjacent, yet not exposed at the view-opening, I term theoperation of selecting the charaoters, and I wish to state at thispoint, that my invention, so far as the concealment of the selectedcharacters and their subsequent exposure by movement of the drawer areconcerned, is not limited to the particular selecting mechanism hereinshown, for I consider any mechanism wherein certain characters are fixedupon or selected prior to the opening of the drawer and thereafterexposed by movement of the drawer as within the scope of my presentinvention.

Referring to Figs. 2 and 3, upon the rear end of the pointer-shaft B ismounted and made fast thereto a printing-wheel D, having upon itsperiphery a series of printing-characters d, similar in number andarrangement to the Visual characters upon the indicatingwheel, so thatwhen certain of the characters of the latter are selected, as described,the corresponding printing-characters will be simultaneously moved intoprinting position.

In connection with the printing-characters d I may use any suitablemechanism for making the desired impression therefrom for a permanentrecord of the successive purchases.

In the particular machine herein shown (see Fig. 4) the printingmechanism consists of a preferably cylindrical rotatable platen d,journaled in the end of the printing-lever d pivoted at (1" upon a studprojecting from one of the back frame-plates b. This lever 01 as hereinshown, has a depending lug d which lies against one side of a dependingarm (i loosely j ournaled upon the said pivot d and of such length thatits end projects below the top of the inclosing case A into the money orchange drawerbaek of the money-tills therein and in position to be actedupon, as will be described, on movement of the drawer, by a suitable camcl". (Shown in full lines, Fig. 4, and in dotted lines, Fig. 2.) Aspring d act ing upon the end d of the lever (1 acts at the proper timeto raise the platen into contact with the characters on theprinting-wheel and to maintain the lug d in proper contact with thedepending gravity-arm d When the drawer is opened, the cam d acts uponand moves the depending gravity-arm d to the right, Fig. at, said armacting through the lug d to turn the lever 61 on its pivot and drop theplaten d away from the characters upon the printing-wheel to enable thelatter to be turned by the pointer into desired printing position. Theplaten is held in its depressed position until the arm (1 is released bythe cam d, which release takes place during the early part of theopening movement of the drawer, when the spring d returns the said leverd and arm (Z to their normal positions, thereby bringing the platenagainst the selected printing-character and making an impression uponthe record-sheet, to be described.

The cylindrical and rotatable platen d, as herein shown, is providedwith a ratchet d cooperating with which is a pawl (Z on the end of thepawl-carrying lever d loosely journaled on the platen-pivot and providedwith a tail, adapted, when the lever (Z is dropped, to contact with aprojection (Z on the frame, so that at each depression of the platent'.e. each time it is moved away from the printing-wheelthe contact of thetail of the pawl-carrying lever with the projection (Z causes the pawlcl to rotate the platen through a distance represented by one or moreteeth of the ratchet, thus presenting a new surface of the platen ateach impression. The lever d is also shown as provided with alocking-finger (V, which, at each upward or printing movement of thelever (1 passes in front of one of a series of locking-pins d on thefront of the printing-wheel,to thereby restrain the said wheel and thepointer b from rotation in the direction of the arrow 10, Fig. 4, saidwheel, with its shaft and pointer, being restrained from rotation in anopposite direction by the spring-controlled pawl (1, Fig. 4:, so thatthe pointer-shaft, with its indicating and printing wheels, can never berotated in a direction opposite the arrow 10, but can be rotated in thedirection of the arrow 10 when the locking-lever (Z is moved bydepression of the platen.

A printing-strip s is carried upon a suitable reel .9 and is passedbetween the platen and printing-wheel and over a suitable feed-roller sto and upon the take-up s geared thereto, (see Fig. 4,) said feed-roller5 being provided with a ratchet s, cooperating with which is a pawl s onan arm .9, adapted to be moved by the projecting end 61 of the lever (Zat each movement of the latter to feed the strip a distance representedby one or more teeth on the ratchet s at each printing movement. Atype-ribbon t is carried by suitable spools If, one of which is gearedto and rotated by the feed-roller the ribbon being fed along by positiverotation of the spool 15 by the said feed-roller. This printingmechanism is in general substantially that shown in my former UnitedStates patent, No. 467,592, dated January 26, 1892, differing therefromin minor details only.

Having now described the mechanism for visually indicating to thepurchaser the amount of purchase and for permanently recording uponpaper the successive purchases, I will now describe the mechanism foradding or summing up the aggregate amount of the purchases, saidmechanism being hereinafter designated as the adding mechanism.

Referring to Figs. 2, 3, 3, and 5, I have in the machine shown erectedupon the inclosing case A an auxiliary frame consisting of twoframe-plates F F, between which, at or near the tops thereof, is held afixed shaft f, upon which are loosely journaled a series, herein shownas four in number, of adding-wheels f,f ,f and f upon the peripheries ofwhich are displayed, in series, figure characters ranging, preferably,from 0 to 9 and representing dollars. Each of these addingwheels isprovided with an attached ratchetwheel f having a number of teethequaling the number of peripheral characters, the number of teeth beingherein shown as ten, one of the notches in each of the wheels, exceptthat of the wheel f, being made deeper than the others, the deep notchesf registering and being themselves graduatedz'. e. ,the notch in theratchet of the wheel f is deeper than that in the ratchet of the wheel fthat in turn being deeper than the notch in the ratchet of the wheel fCooperating with the ratchet-wheels f is a single pawl f (see 2 and 5and 7 to 10,) having four fingers adapted to engage the four ratchets,the depending ends of the four fingers being of different lengthscorresponding to the different depths of the notches f in theratchet-wheels, the said pawl f being pivoted at f on the ends of thearms f pivoted at f to one of the frame-plates F, one of said armshaving a depending tail portion f, to which is c011- nected a spring fto retain the pawl f normally in its elevated position. Reciprocation ofthe pawl f causes step-by-step rotation of the ratchet-wheel f of theadding-wheel f through nine steps until its pawl reaches the deep notchf therein, when the next step permits its pawl to drop into the saidnotch, and thereby bring the end of the next arm of the pawl intoengagement with the ratchet f of the second wheel f to rotate the latterone tooth, and so on throughout the entire series, each completerotation of one wheel causing a rotative movement of one step of thewheel of the next highest denomination.

I do not claim this particular construction of adding mechanism as apart of my invention, as the same is in substance a wellknownconstruction.

Retrograde movement of the adding-wheels is prevented by suitablespring-controlled pawls f which engage the several ratchetwheels.

To each of the adding-wheels f, f f and f I have added a star-wheel g,cooperating with which are suitable V-shaped projections g on the armsor levers f", which, whenever the said levers are raised to cause aforward movement of one or more of the addingwheels, enter between twoof the V-shaped projections on their respective star-wheels to preventexcessive movement of the addingwheels. IVere it not for this themomentum acquired during the step-by-step rotation of the wheels mightbe suificient at times to cause said wheels to move two or more steps,the projections g, however, acting, in connection with the star-wheelsreferred to, to limit any rotative movement of the addingwheels to adistance represented by one of the notches of the ratchet-wheels.

Figs. 7, 8, 9, and 10 represent the engagement of the arms of the pawlwith the successive wheels of the series during rotation of the addingmechanism. In Fig. 7 the next forward movement of the pawl will causeone of its arms to drop into the deep notch f of the ratchet-wheel f ofthe first addingwheel, thereby bringing the second arm of the pawl intoengagement with the teeth of the second adding-wheel, as shown in Fig.8, to rotate the latter one tooth, one complete rotation of the secondwheel permitting the IIO second arm to drop into the notch f therein toenable the third arm to engage the teeth of the third wheel, the latter,in turn, at the end ofone complete rotation dropping into a notch in thefourth wheel, which latter has no deep notch, there being no wheel ofhigher denomination.

The pawl-carrying lever f is moved to impart a step-by-step movement tothe addingwheels referred to by means of pins 7L (shown as five innumber) upon the side of a toothed wheel 7L, loosely journaled on theend of a fixed shaft 71 mounted in the frame-plates F, said wheel hbeing geared to a second wheel 7L3, (shown as of the same diam eter,)and upon the periphery of which are displayed as many series ofcharacters corresponding to the characters on the indicating and printing wheels and the fixed dial as there are pins h on the wheel 7L,(herein shown as five in number,) the said characters on the secondwheel 7L3 in the present instance representin g cents in multiples offive. 6., amounts less than one dollarwhile the characters on theadding-wheels f, f, f", and f referred to, indicate the aggregate numberof dollars.

It is stated above that the series of characters on the wheel 7L3 aresimilar to those on the indicating wheel and dial. This is true with oneexception viz., the twentieth character on the wheel 72, instead ofbeing 1.00, as on the indicating wheel and dial, is 00, the l for thedollar being displayed by the first wheel of the adding device adjacentto it.

The wheels 7t and 71 are rotated to bring the characters correspondingto the selected characters on the in d icating-wheel into properposition by means of an L-shaped pawl 71., (see Fig. 6,) pivoted at 7rto the arm h" fast on the end of the shaft h on which the wheel h isloosely journaled, the said shaft being surrounded by a coiled spring 71(see Fig. 5,) which acts to throw the said arm to the right, Fig. 6, inthe direction of arrow 25 to draw the pawl 71 in the same direction backover the teeth of the wheel 72. without contact therewith.

The depending end of the L-shaped pawl 7r is provided with a roller 71adapted to be engaged by a striker-plate 71" on the drawer, (see Figs. 3and 6,) said striker-plate,as shown, having a gradually-inclinedport-ion at its front end, to be referred to. The shaft 7L2 also hasfast upon its end an arm 71 (see Fig. 3,) which, by the action of thespring 71 referred to, is maintained always in firm contact with aprojecting pin 71 on a vertical slide-rod 71 mounted to slide insuitable bearings on the inside of the front frame-plate I), (see Fig.3,) which slide-bar, as herein shown, has a projecting ear 7L (see Fig.3,) acted upon by a spring 7t surrounding a fixed spindle 71 whichspring acts to normally raise the said slide-bar and maintain it inconstant contact with a snail-like cam H fast on the pointershaft. Thespring 71. tending to raise the slide-bar and keep it in contact withthe bar being stronger than the spring 71 surrounding the shaft 71. onwhich the arms 7L6 and 71. are mounted, acts to raise the pin 71. andthrough. the arm 71 rotate the shaft 71. with its pawl-carrying leverand pawl in the direction of the arrow, Fi 6, whenever the cam H permitsthe said slide-bar to be raised, and when the said cam depresses theslide-bar against the action of the spring h the spring 71 causes theshaft 71 to be rotated to permit its arm 7t to follow the downwardmovement of and in contact with the pin 71 and cause the pawl-carryinglever and pawl to be moved to the right, Fig. (3, or in the direction ofthe arrow 30, into or toward the position shown in Fig. 3, to move thepawl back into position to engage and subsequently impart feedingmovement to the wheel 71".

A spring h surrounding the pivot h on the pawl 7& acts to maintain thelatter normally out of engagement with the teeth of the wheel 71., thelimit of movement of the said pawl with relation to the saidpawl-carrying lever being fixed by a pin 71 (see Fig. 6,) which works ina notch 72 in the end of the pawlcarrying lever 71".

The snail-like cam II has as many radii as there are characters on theindicating and printing wheels, the successive radii being uniformlylonger than the radii preceding them, as shown in dotted linesFig. 5.

Assuming the parts to be in the position shown in the drawings, theoperation of the adding mechanism is as follows, viz: hen thepointer-shaft B is rotated to select a character, as described, the camH depresses the slide-bar 72. and thereby the pin 7t, permitting thespring h to rotate the shaft 7L2, with its pawl-carrier, to the right,in the direction of the arrow 30, Fig. 6, adistance correspondin g tothe distance through which the cam has been turned. hen the drawer issubsequently open ed, the striker-plate h engages the roller 71 in theend of the pawl h in its position at the right, and the pawl-spring,being weaker than the spring 71 controlling the pawlcarrier, permitssaid pawl to be first turned on its pivot h into engagement with theteeth of the wheel h, further movement of the drawer and striker-platepushing the pawl in engagementwith the wheel, together with thepawl-carrying lever, before it into its dotted position, Fig. 6, therebyrotating the wheels h and 7L3 through a distance determined by thelength of the retrograde movement of the pawl-carrying lever by the camH, such rotation of the wheel 7L3 bringing into reading position acharacter thereon corresponding to the character selected by thepointer. In the present instance each tooth represents one character onthe face of the wheel ha, and there being twenty characters, movement ofthe twenty teeth represents movement through one entire series ofcharacters thereon, and causes a movement of the IIO first adding-wheelof one tooth, indicating an amount of sales of one dollar. Aspringcontrolled pawl f", cooperating with the wheel h, preventsretrograde movement of the said wheel. It is evident that the farther tothe right, Fig. 6, the pawl-carrying lever 71/6 is permitted to move bydepression of the slide-bar h by the cam the longer will be the throw ofthe pawl and the corresponding movement of the wheel. Movement of thepointer to the first character, or 5, on the dial causes the cam todepress the slide-bar sufficiently only to permit the pawl to move tothe right, Fig. 6, through one tooth, to thereby cause a subsequentfeeding movement of one tooth when the draweris opened, whereas amovement of the pointer to the character marked $1.00 on the dial wouldcause the cam H to depress its slide-bar sufficient to permit thepawl-carrying lever h to move back to the right over twenty teeth,thereby causing a feeding movement of twenty teeth on the wheel 71 whenthe said lever is subsequently acted upon by the opening of the drawer,each tooth in the machine shown representing five cents. A stop-arm f011 the shaft 7L2, and shown in dotted lines, Fig. 6, cooperates with astop f on one of the frame-plates F to limit the backward movement ofthe pawl-carrying lever h i. 6., the movement of the said lever to theright in the direction of the arrow 30 thereon. It will be noticed thatthe striker-plate h has a long straight top, over which the roller it onthe pawl b may ride after the said pawl and pawlcarrying lever have beengiven their full movement to permit full opening of the drawer withoutdanger of breaking any of the parts.

Having now described in detail the opera tion of the independent partsof my machine, I will proceed in a few words to describe the generaloperation of the machine.

Assuming the parts to be in the position shown in the drawings, the 5displayed in the view-opening c on the dial Z2 on the faceplate of theinclosing case indicates, visually, the amount of the last purchase, thedrawer being closed. The pointer shaft B, being locked against rotationby the locking-lever c1 and projection d Fig. 4, cannot be rotated untilafter the drawer has first been opened and stopped by engagement of thehooked end a of the locking-lever with the stop a, said movement actingthrough the cam (Z 011 the depending arm d to pull down theprinting-lever d and remove the lockingfinger d to release thepointer-shaft, and simultaneously therewith the inclined portion of thetrack 0 by movement of the drawer drops the roller 0 and the verticalslide-rod 0 to permit the spring 0 Fig. 5, to move the indicating-wheelback on the said shaft B into position, with its pin 0 in contact withthe left ear I), as previously described. The operator may now turn theindicating-pointer b to the right to select a character corresponding tothe amount of a new purchase, said character thus selected being movedinto position next to the view-opening 0, yet still concealed within theinclosing case, as described. The operator having opened the drawer thusfar is prevented from again closing it without making his change byengagement of a swinging pawl 19, Fig. 3, carried at the back of thedrawer, with a rack 29' on the bottom of the drawer-case, so that it isnecessary for the operator to completely open the drawer in order tocarry the said pawl beyond the front end of the rack, the pawl in themeantime trailing over the teeth of the rack and preventing the drawerfrom being pushed in. This full opening of the drawer operates, throughthe pawl h in the manner described, to release the lever (1 Fig. 4, andpermit the platen to be thrown by its spring 61 against theprinting-wheel to make a permanent record upon the paper sheet and atthe same time by its finger (1 again lock the pointer-shaft againstrotation, and the said drawer immediately thereafter, acting through thestriker-plate h and pawl 71', rotates the wheels h and 703 a distancecorresponding to the depression of the slide-rod 7t by the cam ll on thepointer-shaft to operate the adding mechanism described. The operator,having fully opened the drawer, is now compelled to deposit the properamount of money in the drawer in order that the amount of money thereinat the end of the day may correspond with the permanent record ofpurchases upon the paper strip and the aggregate amount of purchasedisplayed by the adding device, and after fully opening the drawer hemust again close the same before the amount of the purchase for which hehas just made change in the drawer can be displayed at the view-openingc and before he can move the pointer for a new purchase, the characterselected by the pointer before the drawer was opened and representingthe amount of the purchase being now exposed at the view-opening by theroller o riding up the incline of the track 0 and raising the slide-rodc to cause the pawl c to move the indicating-wheel on and with relationto the pointer-shaft through a distance represented by the lost motionbe tween the pin 0 and the cars 19 which is sufficient to move theselected and concealed character into exposed position, as shown in Fig.1, back of the view opening. During the closing of the drawer theswinging pawl 19 drags over the rack 19, but now in an oppositedirection, and while permitting the drawer to be closed the same pawlacts to prevent the drawer being opened until it has been pushed in orclosed sufficiently to pass the pawl beyond the inner end of the rack,as shown in Fig. 3. It will thus be seen that a single pawl 19, bydragging first in one and then in the other direction over a single rack19, prevents, in the one instance, closing of the drawer until it hasbeen fully opened, and in the latter instance opening the drawer untilit has been fully closed, thus effecting, in a much simpler form, whathas hitherto been accomplished by the use of double racks and pawls.

The plate or shield a Fig. 3, prevents the operator depressing thelocking-lever a for the initial opening of the drawer and therebyraising its hooked end, so as to permit the drawer to be drawn straightout instead of being stopped at the proper point by the stop 7L6, as itmust be to permit the selection of the proper character.

The inclosing case, within which the indicating-wheel rotates,constitutes one form of screen, back of which the selected charactersare concealed until exposure of the same is effected by opening of thedrawer.

lVhile I have embodied my invention, with its various features, in amachine such as herein shown, because such machine is simple inconstruction and operation and inexpensive, a single dial, pointer andprinting-wheel representing the entire range of the machine, yet myinvention, as claimed, is not restricted to this particular constructionor type of machine, for my said invention may be used in connection withany type or construction of machine for which it is adapted.
